Despite the ringing endorsement by a certain member who shall remain nameless. I now have garbage in between my engine and tranny. Yes garbage. What good is a racing clutch when you can't shift at high RPM. USELESS!!!!!!! Should have just listened to the crowd and went exedy twin. Expensive but way cheaper than doing it twice. #LessonLearned Thank you ACT for ruining a other wise nice day at the track.

 

my car cant shift at high rpm either. It make a grinding sound. Change the trans oil couple times, problem still occur. Have no idea what clutch is in the car, but it can handle 450lbs torgue on the dyno thou. Is exedy twin is the only clutch recommend for evo?? Its kinda expensive .

 

Had the same issue when I had the act... went to an exedy triple and I will never look back.. goodluck man!!

 

How high of an rpm are we talking?

 

atleast over 5k

 

i have an ACT HDSS and theres no problems..... if anything i thought people said act was better and that exedy wears out faster because of the way they're designed.

 

i have an ACT heavy duty street disk and streetlite flywheel. although not a big fan of the ACT, mine hasnt shown any lock out issues yet. have you guys tried bleeding and adjusting your clutch? the only thing i have to complain about is the decel chatter i got after installing the clutch.

 

^^when my engine come out, i have my mechanic check on the clutch, thanks

 

So glad you posted this.I just picked up an Exedy twin as I was a little nervous about pushing the ACT single.My feelings were just confirmed.

 

yea ive had this clutch for about 6 months and Im gonna give it one more track day after that if it doesnt shape it its getting the boot.

 

I got the ACTTTP....I had installed by them..never had any lockout issues whatsoever...im more than happy with my ACT,,Sorry to hear that yours isnt what you hoped for....Justin

 

i have an ACT HD w/6-puck and had my stock flywheel resurfaced. This clutch grabs real hard and is holding up strong(knock on wood). Ive been to 2 track visits(drag strip) and havent had any issues.

 

I am running the ACT also and have no issues shifting at 7800 rpm...

 

5K rpms!?
Did you adjust the pedal?

 

^everyone said, my pedal are pretty high, might need adjustment. thanks
